Connector Terminal Geometry for Error-Proof Mold Placement

The patent applies asymmetry by making the first terminal have a non-linear extension shape with varying thickness, while the second terminal has a linear extension shape. This asymmetric design ensures that each terminal has a unique geometry that corresponds to its specific arrangement hole, preventing the first terminal from being mistakenly inserted into the second terminal's arrangement hole. The different shapes create inherent directional guidance and positioning features that eliminate arrangement errors during the molding process.

The patent applies local quality by creating a thickness variation in a specific region of the first terminal. The first terminal has a first region with a first thickness and a second region with a second thickness that is different from the first thickness. This localized thickness change provides a distinctive geometric feature that enables differentiation from the second terminal during arrangement, while the majority of the terminal structure can still be manufactured with standard uniform dimensions, maintaining ease of manufacture.
